The special Forgery gimmick allows you to perform many different, stunning effects, including these three:

1) A spectator pics a card (no force). It is returned to the deck and the magician finds a card that is not the spectator's. This card is signed by the spectator. The magician then simply and stunningly transforms the signed card into the spectator's selection - with the spectator's initials on it!

2) A card passes between two others and magically turns over. This looks like like card warp - but is much stronger. The cards are not folded, and the effect is very, very visual.

3) A card is selcted and placed on the table and then an alternative card is signed. Then the signature magically jumps to the tabled card.
